摘要
眼科与视光学仪器的合理运用，对相关疾病的诊治具有重要意义。仪器临床评估的主要内容包括仪器测量的精确性和准确性，精确性又包括测量的重复性和再现性评估2个方面，而准确性主要涉及仪器间的一致性比较。随着新技术和新仪器迅速发展，相关研究层出不穷，然而在评估方法的选择上亦暴露出不少问题。现就精确性和准确性评估的几种重要统计分析方法进行介绍，并分别举例说明其在临床科研中的合理选择和应用，同时讨论眼别选择和样本量计算对仪器评估的影响，以促进该类研究的规范化发展。
The proper uses of ophthalmic and optical instruments play an important role in diagnosis and treatment of eye diseases. Precision and accuracy assessment are the major indicator for evaluation of instruments. The former consists of repeatability and reproducibility, while the agreement assessment decides its accuracy. There are so many studies focused on this field due to the rapid development of new techniques and instruments, followed by the arising of problems in method selection. This article introduces the main methods of precision and accuracy assessment. And we also provide the ideas of proper method selection in clinical practice and research with examples. Moreover, we discussed the influence of analytic approach with one eye or two, as well as sample size calculation.
